shaded in light blue in the figure below.

Conditions for Multifeed Detection
Multifeed is an error where two or more sheets are fed through
the ADF at once. When a different document length is
detected, this detected result is also called a multifeed.
Multifeed detection is performed by either checking the
overlapping of documents, length of the documents, or the
combination of both. The following conditions are required for
an accurate detection.
Detection by Overlapping
Paper weight: 40 to 209 g/m
2
(11 to 56 lb) (0.05 to 0.250 mm/0.002 to
0.010 in.)
Do not punch holes within 35 mm (1.97 in.) over the center of the
document. See "Fig. 1" (page 39).
Do not attach other documents within 50 mm (1.97 in.) over the
center of the document. See "Fig. 2" (page 40).
Detection by Length
Load documents of the same length in the ADF paper chute (feeder).
Variance in document lengths: 1% or less
Do not punch holes within 35 mm (1.97 in.) over the center of the
document. See "Fig. 1" (page 39).
Detection by Overlapping and Length
Load documents of the same length in the ADF paper chute (feeder).
Paper weight: 40 to 209 g/m
2
(11 to 56 lb) (0.05 to 0.250 mm/0.002 to
0.010 in.)
Variance in document lengths: 1% or less
Do not punch holes within 35 mm (1.97 in.) over the center of the
document. See "Fig. 1" (page 39).
Do not attach other documents within 50 mm (1.97 in.) over the
center of the document. See "Fig. 2" (page 40).
ATTENTION
The above condition applies when the document is set to the center of
the pick roller width.
HINT
If there are any holes in the 35 mm-wide central column, you can move
the document to the left or right to avoid an error.
